Yes every thing is standard distribution, First tomcat isn't starting and I checked the catalina.log to view whats the problem.

Any ways I have solve the problem, it was Mcafee antivirus that is blocking the ports and access.

I am trying to run tomcat 5.5 using JDK 1.5 on windows vista but I am getting permission denied : listening failed error?

I have turned off the firewall but the problem still persists?
How to solve this problem?

Hello,

When I am sending mails from my website and I get the following error message:
-------------------------------------------------------------
Could not connect to SMTP host: mail.sdfpak.org,
port: 25;
nested exception is:
java.net.ConnectException: Connection refused
javax.mail.MessagingException: Could not connect to
SMTP host: mail.sdfpak.org, port: 25;
nested exception is:
java.net.ConnectException: Connection refused
at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:695)
at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:168)
at
javax.mail.Service.connect(Service.java:227)
at
javax.mail.Service.connect(Service.java:131)
.
.
.
.
-------------------------------------------------------------

One thing is worth noting that I can send emails from my local machine using same smtp server after authenticating the server. But SMTP connections are refused on the machine where I have hosted the website.

Any ideas how to solve this problem or what is causing it?

When I send email from my local system it gives me following error. I have checked all the email addresses are ok, I couldn't find any reason why this is happening, as this is perfectly running on diiferent systems.

The error is :
javax.mail.NoSuchProviderException: No provider for Address type: rfc822

Is there any issue of security envloved in it i.e. rights or firewall blocking?

Thanks in advance for the help.

Hello All,
I am using following code in my my jsp file:
AccessController.checkPermission(new FilePermission("\\h01\dir1", "write"));
first i try it by sharing "\\h01\dir1" as readonly--->it thrown access control exception [thats ok]
but when i try it by sharing "\\h01\dir1" as full control ---> it again thrown access control exception [that should not happen]
i have only used the above line, nothing else [no stuff related to security manger]. Can any one tell me how to remove this issue.
Thank you,

Hello,
I am using JAVA Stored Procedures, to execute the Oracle EXP.exe utility for taking backups.
My JAVA source file is like this:
----------------------------------------------------------
import java.io.*;
import java.util.*;
import java.security.*;

public class Hello
{
public static void printHello ()
{
String prtString="Hello World";
System.out.println(prtString);
}
public static void backup()
{
try
{
System.out.println("Backup Start");
String exp []= {"EXP.exe","HR/HR","GRANTS=Y","TABLES=(EMPLOYEES)"};
Runtime.getRuntime().exec(exp);
System.out.println("Backup End");
}
catch (IOException ioe)
{
System.out.println("IO Exception Caught: " +ioe.getMessage());
}
catch (AccessControlException ace)
{
System.out.println("Access Control Exception Caught: " +ace.getMessage());
}
catch (Exception e)
{
System.out.println("Exception Caught: " +e.getMessage());
}
}
}
----------------------------------------------------------
and i have made two procedure to publish my JAVA Procedures that those are:
----------------------------------------------------------
CREATE OR REPLACE PROCEDURE printHello
AS LANGUAGE JAVA
NAME 'Hello.printHello()';
/
CREATE OR REPLACE PROCEDURE backup
AS LANGUAGE JAVA
NAME 'Hello.backup()';
/
----------------------------------------------------------
I am executing these procedures like this:
----------------------------------------------------------
SQL> call printHello();
Hello World
Call completed.
SQL> call backup();
Backup Start
Access Control Exception Caught: the Permission (java.io.FilePermission <<ALL
FILES>> execute) has not been granted to HR. The PL/SQL to grant this is
dbms_java.grant_permission( 'HR', 'SYS:java.io.FilePermission', '<<ALL FILES>>',
'execute' )
Call completed.
----------------------------------------------------------
I am getting this File Permission exception on executing backup() procedure. I don't know how to solve the problem, i have try the method "dbms_java.grant_permission( 'HR', 'SYS:java.io.FilePermission', '<<ALL FILES>>',
'execute' )" but the issue remains there.
One more thing, I have executed the "backup()" method using JDK, its working but when i try this on ORACLE JVM the exception is thrown.
Waiting for your comments, and if you have other solution please tell me.
